The modulus of elasticity is calculated by dividing the stress by the strain, where . M = modulus of elasticity (ISO 9856) F = force (N) ε elast = elastic elongation at the end of the specified number of cycles (N/mm). In other words: The higher the modulus the lower the elastic elongation per unit stress.

A mass balance, also called a material balance, is an application of conservation of mass to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this technique. The exact conservation law used in the analysis of the system depends on the context of the problem ...

Roller mills may have from one to five rolls that grind pigments into vehicles. Most coating manufacturing facilities that use roller mills operate with conventional three-roll mills. Roller mills are labor intensive, requiring highly skilled operators. Their lack of speed and high operating cost make them unsuitable for large-volume production.
